Not sure if a regex is appropriate here, since some of the symbols come and
go, depending on the compiler, dependencies and architecture.

But I'll take look, thanks for the hint.

I'll raise the issue on the developer's issue tracker and see if I can send
them a patch. Far too much time has been wasted on this already.
